A ship which sank almost two decades ago has caused an oil spill off Panglao, Bohol, the Philippine Coast Guard (PCG) said.
PCG spokesperson Cmdr. Armand Balilo said the spill originated from cargo ship M/V Wilcon, which sank off Barangay Tangnan in Panglao in 1994.
Balilo said the oil slick measured 50 by 25 meters during the last inspection.
He said the recent earthquake in the province may have triggered the vessel to release oil.
